Projects the bounding box edges of this entity and the entityPointer entity onto the projectionPlane, finds the intersection points, and then projects the intersection points back onto the appropriate bounding box edge of this entity.
All points appended to the points array are on the bounding box edges of the entity. The projections are done parallel to the projectionPlane's normal vector.
Public Function BoundingBoxIntersectWith( entityPointer As Entity, intersectType As Autodesk.AutoCAD.DatabaseServices.Intersect, projectionPlane As Plane, points As Point3dCollection, thisGraphicSystemMarker As IntPtr, otherGraphicSystemMarker As IntPtr ) As void
public void BoundingBoxIntersectWith( Entity entityPointer, Autodesk.AutoCAD.DatabaseServices.Intersect intersectType, Plane projectionPlane, Point3dCollection points, IntPtr thisGraphicSystemMarker, IntPtr otherGraphicSystemMarker );

Parameters |
Description |
|
Entity entityPointer |
Input entity with which "this" entity will intersect |
|
Autodesk.AutoCAD.DatabaseServices.Intersect intersectType |
Input requested intersection type |
|
Plane projectionPlane |
Input projection plane for the apparent intersection of the two entities |
|
Point3dCollection points |
Output with the points (in WCS coordinates) of intersection appended |
|
IntPtr thisGraphicSystemMarker |
Input GS marker of subentity of "this" entity that's involved in the intersection operation. May be 0 if not applicable |
|
IntPtr otherGraphicSystemMarker |
Input GS marker of subentity of the entity pointed to by entityPointer that's involved in the intersection operation. May be 0 if not applicable |
The possible Intersect values for intersectType are:
|
Intersect.OnBothOperands |
Do not extend either this entity's bounding box edges nor the entityPointer entity. This results in only calculating intersections where the bounding box lines actually intersect with the entityPointer entity. |
|
Intersect.ExtendThis |
Extend this entity's bounding box edges (if necessary) when calculating intersections, but do not extend the entityPointer entity. |
|
Intersect.ExtendArg |
Extend the entityPointer entity (if necessary) when calculating intersections, but do not extend this entity's bounding box edges. |
|
Intersect.ExtendBoth |
Extend both the entityPointer entity and this entity's bounding box edges (if necessary) when calculating intersections |
